FreeCAD stl slices as solid not hollow

[Valkrider 1]

I have read the other posts on this hollow / solid slicing problems and not had any success sorting my stl out.

 

I ran it through https://service.netfabb.com/login.php 

 

It still has the same problem even with the corrected file. (attached to this post)

 

Any suggestions most welcome.

The STL is a solid block, so why should it slice as hollow?

Have you designed it as hollow? Can you post a screenshot of the model in Freecad which shows that it is hollow?

Thanks I didn't get notified of your reply. Attached is a screenshot as requested.

Strange, maybe a problem in the model itself and the repair made it solid`? The problem is often that the model is not a closed, airtight body, some faces are open and such things.

 

But I don't use FreeCad so I have no idea where you could check it.

 

But your STL you posted above is a solid one:

Thanks for the thoughts, before the repair it was solid too. I will try redesigning it.

Maybe try an easier shape/model just to get a feeling what is important.

I will give designing it a try in 360 or tinkercad but I will have to learn them first 😉

For the beginning use tinkercad, it is much easier to learn.

Otherwise Fusion is so powerful, so you should definitely learn it.

I ended up trying it in both TinkerCad and Fusion360 and gave up too steep a learning curve and too different to FreeCAD. So I re-drew it in FreeCAD doing it differently and it sliced fine and is now printing. 😀

 

Thanks for all the help and suggestions.

Glad it worked!

When you know FreeCad it makes no sense to learn another software when you are happy with it.
